Usage guidelines
If the VLAN configuration or flow table configuration of an activated OpenFlow instance is changed, use this command to reactivate the instance. After the OpenFlow instance is reactivated, it re-establishes connections to controllers if the OpenFlow instance was connected to the controllers before the reactivation.
Reactivating an OpenFlow instance refreshes the configuration data and interrupts communication with the controllers.
Examples
# Activate OpenFlow instance 1.
<Sysname> system-view
[Sysname] openflow instance 1
[Sysname-of-inst-1] active instance
classification global
Use classification global to configure the global mode for an OpenFlow instance.
Use undo classification to restore the default.
Syntax
classification global
undo classification

controller address
Use controller address to specify a controller for an OpenFlow switch and configure the main connection to the controller.
Use undo controller address to delete the main connection to the specified controller.
Syntax
controller controller-id address { ip ipv4-address | ipv6 ipv6-address } [ port port-number ] [ local address { ip local-ipv4-address | ipv6 local-ipv6-address } [ port local-port-number ] ] [ ssl ssl-policy-name ] [ vrf vrf-name ]

Parameters
controller-id: Specifies a controller by its ID in the range of 0 to 63.
ip ipv4-address: Specifies the IPv4 address of the controller.
ipv6 ipv6-address: Specifies the IPv6 address of the controller.
port port-number: Sets the port number used by the controller to establish TCP connections to the OpenFlow switch. The value range for the port number is 1 to 65535. The default value is 6633.
local address: Specifies the source IP address used to establish TCP connections to the controller. When multiple routes are available between a controller and a switch, you can use this keyword to configure a source IP address for the switch. When the switch restarts or an active/standby switchover occurs, the switch can use the original route to reconnect to the controller without selecting a new route.
ip local-ipv4-address: Specifies the source IPv4 address.
ipv6 local-ipv6-address: Specifies the source IPv6 address.
port local-port-number: Specifies the source port number in the range of 1 to 65535. If you do not specify this option, the system automatically assigns a source port number for establishing the main connection to the controller.
ssl ssl-policy-name: Specifies the SSL client policy that the controller uses to authenticate the OpenFlow switch. The ssl-policy-name argument is a case-insensitive string of 1 to 31 characters. You must configure a separate SSL client policy for the main connection to each controller.
vrf vrf-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VRF name, the controller is in the public network.
Usage guidelines
You can specify multiple controllers for an OpenFlow switch. The OpenFlow channel between the OpenFlow switch and each controller can have only one main connection.
The OpenFlow switch uses the main connection to a controller to exchange control messages with the controller to perform the following operations:
· Receive flow table entries or data from the controller.
· Report information to the controller.
As a best practice, configure a unicast IP address for a controller. An OpenFlow switch might fail to establish a connection with the controller that does not use a unicast IP address.
As a best practice, configure a unicast source IP address that is the IP address of a port belonging to the OpenFlow instance. If the source IP address is not a unicast address of a port belonging to the OpenFlow instance, the OpenFlow switch might fail to establish a connection with the controller.
Examples
# Specify controller 1 for OpenFlow instance 1. The controller's IP address is 1.1.1.1 and the port number is 6666.
<Sysname> system-view
[Sysname] openflow instance 1
[Sysname-of-inst-1] controller 1 address ip 1.1.1.1 port 6666
controller auxiliary
Use controller auxiliary to specify a controller for an OpenFlow switch and configure an auxiliary connection to the controller.
Use undo controller auxiliary to delete the specified auxiliary connection to the specified controller.
Syntax
controller controller-id auxiliary auxiliary-id transport { tcp | udp | ssl ssl-policy-name } [ address { ip ipv4-address | ipv6 ipv6-address } ] [ port port-number ]
undo controller id auxiliary auxiliary-id
Default
An OpenFlow instance does not have auxiliary connections to a controller.

Parameters
controller-id: Specifies a controller by its ID in the range of 0 to 63.
auxiliary auxiliary-id: Specifies an auxiliary connection ID in the range of 1 to 255.
transport: Specifies the transport layer protocol.
tcp: Specifies TCP connections.
udp: Specifies UDP connections.
ssl ssl-policy-name: Specifies the SSL client policy that the controller uses to authenticate the OpenFlow switch. The ssl-policy-name argument is a case-insensitive string of 1 to 31 characters.
ip ipv4-address: Specifies the IPv4 address of the controller.
ipv6 ipv6-address: Specifies the IPv6 address of the controller.
port port-number: Sets the port number used to establish TCP connections to the controller. The value range for the port number is 1 to 65535. The default value is 6633.
Usage guidelines
The OpenFlow channel might have one main connection and multiple auxiliary connections. Auxiliary connections are used to improve the communication performance between the controller and OpenFlow switches.
Make sure the configuration of an auxiliary connection does not conflict with the configuration of the main connection. Otherwise, the auxiliary connection cannot be established.
An auxiliary connection can have a different destination IP address and port number than the main connection. If no destination IP address and port number are specified, the auxiliary connection uses the destination IP address and port number configured for the main connection.
Examples
# Specify controller 1 for OpenFlow instance 1 and configure auxiliary connection 1 to the controller.
<Sysname> system-view
[Sysname] openflow instance 1
[Sysname-of-inst-1] controller 10 auxiliary 1 transport tcp

Parameters
multiple: Specifies the multiple mode.
single: Specifies the single mode.
Usage guidelines
In single mode, the OpenFlow switch connects to only one controller at a time. When communication with the current controller fails, the OpenFlow instance connects to the controller with the lowest ID among the rest controllers.
In multiple mode, the OpenFlow switch simultaneously connects to all controllers. If one or more controllers become invalid or disconnected, the OpenFlow switch continues to exchange messages with the rest of the controllers.
Examples
# Set all controllers of OpenFlow instance 1 to operate in single mode.
<Sysname> system-view
[Sysname] openflow instance 1
[Sysname-of-inst-1] controller mode single
